So who thinks my new BOV is gonna be louder than an asian girl having ---- sex with a black man for the first time*? It's a Greddy Type RS. Haven't put it on the car since Tim welded the flange on for me Sunday because the weather has been **** all week. The horn on it has me concerned as do the holes drilled in it. Are those there to make it whistle? anyone got one of these?









* btw, that's not the sound I am looking for. I prefer a quieter BOV.

 

I'm just guessing here, but maybe you will hear it over your exhaust.

 

Oh yeah, the exhaust. You won't here the BOV. haha.

Unscrew the blue horn to see if it quiets it down.

 

I would call it a "middle of the pack" as far as loudness. With the RFL leading the pack and the bosch being the quietest.

 

The holes (and for that matter, the horn itself) are there to make noise. Period.

I have a Chinese knockoff of the same BOV- it's of surprisingly good quality, pretty much indistinguishable from the genuine article except without the word Greddy cast in the side. I removed the whistle-tip and made a threaded adapter on the lathe to fit a small K&N air filter on the exhaust. It's much quieter / less annoying now. Still louder than a recirculated Bosch, but when it vents it's just a nice, mellow *pssht* as opposed to a *fweeeeeeem!* I think you can buy these adapters on eBay rather cheaply.

Also, consider opening up the BOV and removing the center (smaller) spring from the inside. This softens it up a great deal (the range of the screw on the top is quite limited) and makes it vent much sooner and more gently.

Nice looking flange, BTW. Tim is a much better welder then I am.

 

Greddy BOVs just sound good, nothing overly loud or fancy....that's why i love my Type-S

 

Yea, nice welds.

 

i have the real-deal RS on mine... love it... not loud enough though lol. Yes it does the "chime" or "whistle" when the last bit of air is going out. I have gotten quite used to the whistle when lifting the throttle (even not in boost), heck i keep expecting the noise when driving my GF's MSM which has a knock off dual-horn RFL......

 

Did you buy it off Ebay? I heard there was a good and bad version. I'd like to get a new BOV, but the $200 can go twords something better.

 

Yes, though it's been so long that I can't remember who the seller was. And I don't know about a "good version" and a "bad version". There are probably more than two companies making these, all I can say is that the one I got was very well-machined and has lasted over a year thus far with absolutely zero problems and zero maintenance apart from the initial springectomy. I kinda figure that at $45 - $55 (typical, including shipping) it's really not a big deal if you have to buy two of them to get one that works- you're still way ahead of the game price-wise.

 

nice comparo to the girl
